Using a test

The Grepper · 04-04-2002, 03:19 PM

Hello, I want to test to see if a file is empty so its file is a size of 0.

im pretty sure its test -s filename, i have to look at the man pages to make sure, but thats not my prob. How would I be able to put test -s file, in an if statement so that if the answer is true, then do something. Ive tried to compare its result to an int, and other means, I just cant figure it out

Thanks a bunch

Code:

if [ -f filename ]
then
  if ! [ -s filename ]
  then
  go make a nice big tasty cake
  fi
fi

but in order to do that I have to use the test

I meant something along the line of

if [ test -s filename -eq 0 ]
that doesnt work

thanks again

[ IS test. it's just an attempt to make it look more like a normal language. try it.
